[Mikenekohanten (Sakamoto Kafka)] Ponkotsu Futa Robot Laboratory Z [MrBubbles]

A deadpan young scientist deploys her clumsy futanari robot with a freshly installed combat module, mechanical wings spread as she launches to face a voluptuous demon supervillain. But the showdown abandons fighting entirely—a skeletal mechanical arm pins and penetrates the sobbing demon girl into an ahegao mess while the flustered robot insists she's only going along with the doctor's hobbies. Part of an ongoing series where every sortie this malfunctioning mecha girl takes dissolves into lewd, chaotic mishaps.
